Lund was a veteran minor-leaguer until the World Hockey Association came into existence in 1972. The upstart league presented opportunities not only for high-profile NHL stars, but minor league and players outside North America as well. Signing with the Houston franchise, Lund has stated that he went from earning $22,000 in the minors to $150,000 in the WHA. Although never playing in the NHL, he was to have a significant career in the WHA as he won the League Championship Avco Cup twice and finishing at #12 all-time in points.

Lund's best season was 1974–75 when he lead his team in points with 108, ahead of the legendary Gordie Howe, to finish fifth overall in league points, he participated in the annual All-Star game and his team won the Avco World Trophy.
